The CanChek system offers superior detection sensitivity and is able to identify a wide range of foreign bodies. Using a horizontal multi-beam system, the CanChek inspects the cross section of the can. Due to the angle of the beams, contaminants are pulled away from the sidewalls, increasing visibility in at least one of the x-ray images. This dramatically increases sensitivity and the probability of detection. CanChek can inspect 1200 cans per minute. Variable speed detection capability allows changes in line speed without interrupting inspection, thereby increasing productivity.
